Areas of Interest
Because I have been involved in system modeling most of my life, my areas of expertise are diverse and includes anything that is complicated and interesting, for example: deterministic and probabilistic simulation, uncertainty and sensitivity analyses, optimization, static and dynamic simulation, coupled processes, integration of submodels, abstraction, model verification and validation, quality assurance, and management systems.
For business I have experience (and am interested) in making businesses more profitable through analyses and simulation (margins, costs, reliability, external economic influences, discrete hazards and events). I am especially interested in helping businesses grow and perform better. In finance, I am interested in modeling of stocks, options, and credit risk (especially for small and medium-sized institutions), portfolio optimization, interest rates, currencies, stochastic volatility, and bringing mortality (health) into financial planning.
In science and engineering, I have experience in most aspects of the performance of nuclear systems including safety and risk assessment, engineered barrier performance and degradation, colloid generation and transport, unsaturated and saturated hydrology and contaminant transport, wasteform performance and degradation, biosphere modeling, features, events, and processes, scenario development and assessment, disruptive events, natural hazards and climate, evapotransipiration and conventional covers, erosion assessment and control, radiation damage, radiolysis, corrosion, geochemistry, impacts of biota, and many, many more areas.
